PPN][Fe3(CO)9(C⋮CH)] and [Fe3(CO)9(C⋮COTi(THF)4Cl)] from the Reaction of Low-Valent Titanium with [Fe3(CO)9(CCO)]2-

Abstract

TiCl3(DME)1.5 (DME = 1,2-dimethoxyethane) and a Zn−Cu couple react with [PPN]2[Fe3(CO)9(CCO)] to give the new compound [PPN][Fe3(CO)9(C⋮CH)] (I) (70% yield), a known compound [Fe3(CO)10(CCH2)] (II) (9% yield), and another new compound [Fe3(CO)9(CCOTi(THF)4Cl)] (III). Compound I was characterized by 1H and 13C NMR, IR, mass spectrometry, and X-ray crystallography. Compound III was characterized by IR, mass spectrometry, 13C NMR, and X-ray crystallography.
